UPDATE
Work on my BCs and Taurus could now be seriously threatened. Damn you Ishkur! 
Here is some concept art fully inspired by Ishkur from his army blog and the tread regarding Chaos Sorcerers and petrification! as discussed here: https://discourse.chaos-dwarfs.com/t/7304
If it comes together I might even make the helm for the petrified sorcerer in the same basic shape as the “tall hats” as noted in my sketch I have a bit for it in mind. Funny thing is the bit is from the classic throne bearers. It was part of one of the bearers then I cut it off. Next stop was for the BCs, didn’t like it there, cut it off again. Next was dry fitting it for either the tenderizer or the whirlwind. That didn’t work either. So maybe 4th time is the charm.
